Spectralon wavelength calibration standard sets consist of three wavelength calibration standards covering the UV-VIS-NIR region of the spectrum. Each wavelength standard is formulated by impregnating a Spectralon substrate with the oxide of a rare earth element which displays sharp absorption spikes at specific wavelengths. Complete absorption spectral data is supplied with each standard.
 
The three standards available are:

• Holmium Oxide - for UV-Vis-NIR calibrations
• Dysprosium Oxide - for NIR calibrations
• Erbium Oxide - for Vis-NIR calibrations

These durable, washable and chemically inert standards are ideal for wavelength calibration of spectrophotometers, reflectometers and other spectral instruments. Custom wavelength calibration standards are available to meet your individual needs. Please contact our Technical Sales Department for more information about custom standards development.

Specifications and Ordering Information 

Wavelength Calibration standards are available in 1.25 or 2.00 inches in diameter. The standards are sold individually, or in sets of three. Each standard is housed in a durable delrin holder with a protective cover.

The Spectralon multi-component Wavelength Calibration Standard combines three rare earth oxides — holmium oxide, erbium oxide and dysprosium oxide — to provide a consistently stable standard that exhibits high resolvable peaks and strong absorbance characteristics. The standard is used for establishing the accuracy of the near infrared (NIR) wavelength scale of reflectance spectrophotometers.

Made from Spectralon diffuse reflectance material, these durable, washable, chemically inert standards are ideal for calibration of monochromators and reflectance spectrophotometer system arrays.

Calibration data for peak absorbance wavelengths and relative to maximum absorbance is provided with the standard. Calibration is traceable to National Research Council, Canada (NRCC) standards.
